We had previously maintained test coverage for macos13 given its large user base. Given that user base has now decreased to <1% of compass usage, we can remove it from our testing matrix

Double check that mongosh is also no longer testing against macos13 https://mixpanel.com/project/3851272/view/4346958/app/boards#id=10927224&timeFilter=%7E%28dateRange%7E%28type%7E%27in*20the*20last%7EexclusionOffset%7Enull%7Ewindow%7E%28unit%7E%27month%7Evalue%7E12%29%29%29&editor-card-id=%22report-88007744%22

Replace with macos14 as the min supported version and update our internal version support matrix and docs accordingly
